[Eviews 7 and 8]Introduction to the problemI am analysing the following time series: 1) Criminality series in UK (for example, theft) every quarter year. 2) Refugee count in UK every year (I used cubic spline to convert it to a quarterly frequency).

Economic theory: According to Becker (1968) and Elrich (1996) criminality study, the entrance of low income people (refugees in this case) with relatively lower scholarity than UK population would increase crime rates in the region.

QuestionI would like to compare both series to identify if the entrance of refugee are statistically increasing the number of the criminality levels in UK. How would you compare both series? Which model would you propose?
